Suggestions please--we just cut up a fresh pineapple that's dry and tasteless. Any ideas for how to use besides compost?

I would return it to the store and get my money back.

What about grilling or broiling it to see if that will bring out any of the sweetness? If you go that route, and it works, this Genius salad is delicious: https://food52.com/recipes/21736-maricel-e-presilla-s-cuban-avocado-watercress-and-pineapple-salad

Put it in a jar with 1/3 Vodka, 1/3 Vanilla Vodka and 1/3 Malibu Rum. Let it infuse for 5 days, add a little pineapple juice, chill and strain for great Hawaiian Martinis.

Or maybe grill it.

Add to a smoothie with other fruit?

Pickle it. Make it into chutney. Use (with some soy/salt, herbs spices) to tenderize steak. Check web for marinade times based on thickneas of cut...it's possible to go overboard and end up with steak mush.
